Answer:
1.56 M
Explanation:
This is a dilution process and so a dilution formula is suitably used as follows C1V1 = C2V2 where
C1 = concentration of the stock solution
V1 = volume of the stock solution
C2 = concentration of the resulting (dilute) solution and
V2 = the volume of the resulting (dilute) solution
C1V1 = C2V2 (Making C2 subject of the formula)
C2 = C1V1/V2
Given: C1 = 5.736 M; V1 = 3 Ml; V2 = (3+8) 11 Ml
C2 = 5.736 x 3 / 11
C2 = 1.56 M
Answer:
10 (idk why an answer choice isn't 10)
Explanation:
-log(0.0001) = 4 pOH
pH = 14 - pOH
pH = 10
Omposition should be it i think
Brass is a homogeneous mixture.
In the liquid state, the copper and zinc formed a solution.
They did not separate from each other when the brass solidified.
Thus, brass is a solid solution.
